Abstract
Apparatus for producing a high velocity stream of gas, for example, for treating a road surface, including an elongate combustion chamber having, along its lower surface, a plurality of discharge orifices, preferably arranged in a line, means to feed combustion gases into the upper portion of the combustion chamber and means to deflect the incoming gases, so that they are distributed within the combustion chamber prior to leaving the combustion chamber through the discharge orifices.
Claims9
Apparatus for producing a high velocity stream of gas, said apparatus comprising:
- (a) a narrow, enclosed combustion chamber which is horizontally elongate and vertically elongate and has an upper portion and a lower surface;
- (b) means defining a multiplicity of discharge orifices through said lower surface arranged in a substantially straight line;
- (c) a plurality of horizontally spaced inlets for feeding a combustible gas mixture into the upper portion of the combustion chamber;
- (d) means enabling the combustion mixture to be ignited within said chamber whereby, in use, combustion of the mixture takes place wholly within the chamber;
- and
- (e) means to deflect the incoming gas mixture, so that it is distributed within the combustion chamber, and whereby the products of combustion leave the combustion chamber through the discharge orifices.
